What does the term 'residual risk' refer to?

The term 'residual risk' specifically refers to the amount of risk that remains after an organization has implemented measures to mitigate or manage that risk. In the context of cybersecurity, this is particularly relevant because even after applying security controls, vulnerabilities and threats may still exist, leading to a potential risk that has not been completely addressed.

Understanding residual risk is crucial for organizations as it indicates the limits of their risk management efforts and helps in the decision-making process regarding further controls or policies that may need to be adopted to achieve desired risk levels. It emphasizes the importance of continuously monitoring and evaluating risks, ensuring that organizations remain aware of their security posture despite implemented controls.

The other options relate to different aspects of risk management, but they don't accurately define residual risk. For instance, the total amount of risk before any mitigative measures represents inherent risk, while the concept of risk that can be completely eliminated does not align with the reality of risk management, where some level of risk is always present. Additionally, the risk associated with unmonitored systems could be seen as a specific scenario rather than a broad definition of residual risk.
